SOFA-BED.

SPECIFICATION forming part of Letters Patent No. 795,199, dated July 18, 1905.

Application led February 16, 1904. Renewed January 7, 1905. Serial No. 240.086.

To all wiwi/17, 'ift may concern.'

De it known that we, JOHN A. CUMLA, a citizen of the United States, and ANDnr-:s P. FRID- s'rnu, a citizen of Sweden, both residents of Everett, in the county of Middlesex and State of Massachusetts, have jointly invented certain new and useful Improvements in Sofa- Beds` of which the following isa specification.

This invention relates to improvements in sofa-beds adapted for use interchangeably as a hed orV sofa, as occasions may require, and it is carried out as follows, reference being hadto the accompanyingdrawings, w herein Figure 1 is a top plan View of the invention shown in position as a bed. Fig. 2 is a cross-section on the line 2 2 shown in Fig. 1. Fig. 3 is a cross-section on the line 3 3 in Fig. 1, showing the back swungI upward to the position of a sofa. Fig. 4 is a cross-section on the line et A in Fig. 1, showing the back swung upward to the position of a sofa; and Fig. 5 is a cross-section on the line 5 5 in Fig. 1, showing the back swung upward in the position of a sofa.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A A represent the front legs, and A A are the rear legs, in a sofabed, as usual. In practice said legs are made of tubular metal, and to the upper ends thereof are secured, respectively, the heads or couplings B B and B B, as shown.

To the upper ends of the legs A A is suitably secured the front bar or rail C, and to the upper ends of the respective legs A A A A are suitably secured the end bars or rails D D, which together constitute the seatframe, to which the spring-mattress E of any well-known form or construction is secured.

F F are the seat ends, secured to the seatl rear legs A' A in any suitable or well-known manner.

H is the back-frame, which serves as the back-support when the device is used as a sofa, as shown in Fig. 3. Said frame H is pivoted in its lower ends at /L /1/ to the couplings B B or to any other suitable part of the rear legs A A, as may be most practical or convenient. In practice we provide the frame H with suitable end wings H H of any desirable shape or size.

I is a spring-mattress secured to the frame H, as usual.

To the inner ends of the back-frame H are secured or made integral therewith ears or projections H H, to which are pivoted at 71. t the screw-threaded rods K K, the forward ends of which are guided in brackets Z (Z, secured to the end rails D D, as shown.

To the forward ends of the rods K K is secured a longitudinal bar 7u, upon which rests loosely the forward end of a transverse bar L, the rear end of which is pivotally connected to the rear bar G, as shown in Fig. 2.

To the sides of the pivoted back-frame H is pivotally connected at m m a 1-shaped frame composed of vertical portions M M and a hori- Zontal bar M. The said I l-shaped frame M M M serves as a support for the swinging' back H when the latter is swung into a horizontal position to be used as a bed, as represented in Figs. 1 and 9..

To the ends of the rear bar G are secured preferably curved or inclined rest-blocks g g, upon which the lower end M of the pivoted frame II M is caused to rest when the backframe H is swung into vertical position for use as a sofa, as shown in Figs. 3 and 5, and while in such position the end M of the frame M M comes to a stop against abutments or stop projections g g on the blocks g g, as represented in Figs. 3 and 5, thus preventing the said frame H from being swung forward beyond a vertical, or nearly so, position when in use as a sofa. Then it is desired to swing the back-frame H from the sofa position (shown in Figs. 3 and 5) to the bed position, (shown in Figs. 1 and 2,) the operator pulls on a knob Q, attached to a cord g, which passes loosely through a guide or eye C on the IOO under side of the front rail (l. The said cord passes around the under side of a pulley O, journaled on the rear lower brace G', and the upper end ot' said cord is suitably attached to an inwardly-projecting arm m. on the horizontal portion M of the swinging frame M after passing loosely around the rear upper bar Gr, or a sleeve Gr, as shown in Figs. l, 2, and 4. By pulling on the cord g the swinging frame M is caused to swing' backward sufiiciently to cause the lower end M thereot` to be released 'from the rest-blocks ,f7 f/ when the back-:frame H is free to swing by gravity to the bed position (shown in Figs. 1 and 2) when the lower end M of the frame M M is caused to rest on the floor, as shown in said Figs. l and 2.

For the purpose of gradually arresting the descent ot' the frame H we interpose between the stationary rear bar (l andr the movable bar a pair of expansive coiled springs P P, as shown in Figs. l, 2, 3, and Said springs also serve the purpose oi' aiding in. swinging the back H from the horizontal to its vertical position when released. In addition to such expansive springs PP we prefer to employ preferably compressiblc spiral cushionsprings K K, arranged upon the rods K K, between the brackets l (l and adjustable nuts K K on said rods K K, as shown in Figs. l, 2, 3, and 5, by the compression of which the descent of the back-trame H is gradually arrested, so as to prevent concussion when the end M of the traine M M reaches the floor. By adjusting the positions of the nuts K K on the rods K K the yielding resistance of thc springs K K may be adjusted according to the weight of the back-frame of the sofa and its connected parts.

Upon the under side of the forward end of the pivoted bar L is a tooth or projection Z, adapted to engage the rear side of the movable bar when the-'traine H is swung to bed position, (shown in Figsl and 2,) thus preventing the back from being raised until said toothed bar L is released from the bar L.

For the purpose of readily raising' the frame H Yfrom the bed position (shown in Figs. 1 and 2) to the sofa position (shown in Fig's. 3 and 5) we use a knob n, attached to a cord N, passing loosely through the guide-eye C on the front rail C and below a lateral projection Z on the pivoted releasing-bar L, as shown in Figs. l, 2, and 4L. The said cord N is guided over the sleeve Gr on the bar (jV and attached at its rear end to the projection m' on the bar M, as shown in Figs. l, 2, and et. In raising the Vframe H from the bed position to the sofa position it is only necessary to pull on the knob a, which causes the cord N when tightened to raise the lock-bar L by contacting the side projection sufficiently to disengage the tooth Z on said bar L from the longitudinal bar l', and by continuing to pull on the knob a of the cord N the frame H is raised into a vertical, or nearly so, position, as indicated in Figs. 2, 3, and 5, causing the lower ends of the pivoted frame M M to come to a rest and locked positions relative to the blocks y g on the bar Gr, as shown in Figs. 3 and 5, in which locked position the frame H cannot be released until the knob Q is pulled for releasing the ends of the pivoted frame M M vfrom the restblocks g g, as herein above described.

For the purpose of properly guiding' the swing-bar M during the adjustment from a sofa to a bed, and vice versa, we interpose between the rear brace or stay Gr and the swinging bar M a connecting mechanism, as follows: To the brace or stay G is pivotally connected a curved rod or bar R, having a slotted perforation fr at its upper end adapted to receive a pin S, attached to a bracket T, secured to the swinging bar M, as shown in Figs. l, 2, and 4.

IV hat we desire to secure by Letters Patent and claim is l. In a sofa-bed, a seat and back pivotally connected, the back having pivoted to it a locking and supporting device, in combination rods pivotally connected to extensions or ears on the back, and movable in guides attached to the seat-franie, a horizontal bar attached to said rods, coiled springs connecting said bar to the rear of the seat-frame and a locking-bar pivotally connected to the rear of the seat-traine and engaging said bar when the back is swung into bed position substantially as described.

2. In a sofa-bed, a seat and back pivotally connected, a yielding frame pivotally connected to extensions on the back, a lockingbar pivotally connected to the bed-frame and adapted to engage said yielding frame when the device is used as a bed, and a raising device consisting of a cord-pull adapted to disengage the( locking-bar and having its rear end attached to a frame pivotally connected to the back and a slotted guide-link pivotally connected to said frame and to a brace or stay on the bed-frame substantially as described and 'for the purpose set forth.

3. In a sofa-bed, a seat and back pivotally connected and a releasing device for lowering the back into horizontal position consisting of a cord-pull having its rear end attached to a projection on a locking and supporting frame pivotally connected to the back, and a guide or pulley intermediate the front and rear ends ot said cord-pull on which the cord is guided during the release of said back from the seatframe substantially as herein set forth.

In testimony whereoi` we have aiiixed our signatures in presence of two witnesses.
